As law enforcement agencies continue their investigation into the horrific shooting that occurred today LAX, more details are coming to light.

FBI sources are identifying 23-year-old Paul Ciancia as the suspected gunman currently in police custody after this morning's violent incident.

According to some sources, the suspected shooter also carried with him a note that expressed a dissatisfaction with government. Apparently the note also implied he had no desire to hurt innocent bystanders, which fits with other reports from witnesses who say they overheard the suspect asking folks whether or not they worked for the TSA.

It's still unclear why this man was apparently so displeased with the government in general and/or the TSA specifically, but, either way, the effects of his alleged actions are absolutely devastating.
